[FeatureRequest] add to_dict to func.Document for CosmosDB

[eavanvalkenburg]

Describe the request: A clear and concise description. It would be great to add a to_dict method to the Document class so that you can immediately pass that into a class constructor with ** and not have to do json.reads(doc.to_json())
